Apple announced Liquid Glass on Monday for all of its devices at WWDC 2025. Perhaps the most noticeable thing about it is that app icons, tab bars, and even the text magnifier you’ll see when you hover over words feel, well, liquid-y and glassy.

Last year, Apple’s WWDC keynote highlighted the company’s ambitious strides in AI. This year, the company toned down its emphasis on Apple Intelligence and concentrated on updates to its operating systems, services, and software, introducing a new aesthetic it calls “ Liquid Glass ” along with a new naming convention.

Apple announced one important — and immediate — upgrade at WWDC this week, the introduction of support for third-party large language models (LLM), such as ChatGPT from within Xcode. It’s a big step that should benefit developers, accelerating app development.
